X^2 - 6X = 7 subtract 7 from each side X^2 - 6X - 7 = 0 easy factor; factors of constant term(-7) add up to coefficient of linear term(-6) (X + 1)(X - 7)
2x = -7 - 8y
7x = 3 x = 3/7

2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
89
No, it is not.
They are equal. 7 squared is 7 x 7, which equals 49. 6 x 7 = 42, plus another 7 = 49.
Yes, y = 4x + 7 is a linear equation.
This is the common form of the Pythagorean Theorem. It describes the relationship between the two legs of a right triangle and the hypotenuse.
Linear. The only power for the variables is 1.
Negative 11
no.
7 The dimension you provide is not a squared dimension but a linear dimension. There are no squared dimensions in a linear dimension. There are 7 linear yards in 21 linear feet, but no squared yards.
(z=-3) and (z=7)
The square root of 149 (7 squared plus 10 squared equals 149).
